Take advantage of the grill to steam your buns at the same time you grill hotdogs. Lightly spritz the inside and outside of the hotdog buns with water. Purchase a new, clean empty spray bottle for spritzing.

Wrap each lightly spritzed hotdog bun tightly in aluminum foil. Place the aluminum-wrapped hotdog buns on the grill for a few minutes, flipping once. Avoid placing the buns directly over the heat source; instead, place them on an upper rack or along the sides of the grill.

Remove the hotdog buns from the grill. Keep them wrapped until just before serving to keep them warm and moist.

Add a few inches of water to the bottom of a pot and bring to a boil.

Place a rack, steamer insert or steamer basket into the pot, making sure it does not come into direct contact with the water. Place the hotdog buns on top of the rack or steam insert, or into the basket and cover the pot with a lid.

Steam the hotdog buns for 30 to 60 seconds and remove from the pan. Serve immediately.

Moisten a paper towel lightly with water by spritzing it with a water bottle or gently flicking a few drops of water on it with your fingers. You want the paper towel slightly damp but not soaked.

Wrap the moistened paper towel around a hotdog bun and put it in the microwave.

Microwave the hotdog bun for approximately 10 seconds; it may need more or less time depending on the model of your microwave. Be careful not to overcook, or the hotdog bun will get mushy.
